How do you replace a head gasket on a Alfa Romeo?
If you remove the head then of course you replace the head gasket. Where can you get sodium silicate to fix a blown head gasket? Know that adding sodium silicate to an engine is only a temporary fix for a blown head gasket and will not permantly fix the problem. The only permanent fix is to replace the head gasket. I would never add any head gasket fix material to any engine.
